Here are several Bangalore (Bengaluru) firms and architects known for sustainable, eco-friendly or biophilic design. I’ve included a short note about their green focus and a source you can follow up with.

• Biome Environment Solutions / Chitra Vishwanath — long-standing Bengaluru practice focused on earth/mud construction, rainwater harvesting and low‑energy, ecology-led design. Good for vernacular/eco-sensitive projects and water management. (en.wikipedia.org)

• EarthSoul Projects — small firm/builders in Bangalore offering eco‑friendly homes, rainwater harvesting, solar, waste-management and green‑material solutions for residences. (Often used for turnkey/house builds.) (earthsoulprojects.com)

• Greenspace Architects — Bangalore multidisciplinary studio that emphasizes binding architecture with nature (landscape integration, natural ventilation and daylighting). Useful for residential and small institutional projects. (greenspacearchitects.org)

• Kham Design — positions itself as an eco-friendly architect/designer in Bangalore with many completed green projects and emphasis on natural materials, light and ventilation. Good for custom homes and interiors. (khamdesign.in)

• IMK / IM Kadri Architects (Bengaluru office) — larger firm practicing biophilic and ecologically-sensitive design, with experience in institutional and healthcare projects that prioritize daylight, natural ventilation and green courtyards. (imkarchitects.com)

• Green Des Lab — sustainability consulting and green-building services in Bangalore (energy/water/green practices and certification support). Useful if you want technical green‑building consulting. (greendeslab.com)

Notes and next steps

• If you want architects who do formal green certification (LEED, GRIHA, IGBC, etc.), tell me which certification you prefer and I’ll pull a short list of firms in Bangalore with that credential and recent project examples. (Certifications and recent project status can change; I can verify current credentials if you’d like.)
• If you prefer I can also: (a) find contact details for 3–5 of these firms, (b) shortlist studios by project type (residential / commercial / institutional), or (c) search for independent eco‑architects/designers in specific Bangalore neighbourhoods.

Which of those would you like next?
